[0001] This invention relates to the field of energy supply device technology, specifically to a multi-energy complementary integrated energy supply system and energy supply method for large-scale industrial parks. Background Technology

[0002] With the advancement of energy structure adjustment, the penetration rate of renewable energy continues to increase. Combined with combined cooling, heating and power technology, distributed renewable energy output can be integrated to reduce operating costs and improve environmental benefits. The park's energy supply system includes a variety of energy supply devices to ensure the operation of the park.

The inner side of the oil-fixing rings is connected to the outer side of the corresponding oil outlet holes and oil seepage holes.

[0020] Beneficial effects

[0021] This invention provides a multi-energy complementary integrated energy supply system and method for large-scale industrial parks. Compared with existing technologies, it has the following advantages:

[0022] (1) The lubricating oil is circulated through the oil outlet and oil seepage holes in the cooling complementary component, and the lubricating oil is discharged from the inside of the compression shell. The hot oil is circulated through the complementary curved pipe, so that the lubricating oil that has just been discharged from the inside of the compression shell passes through the air pressure output pipe, and then the lubricating oil and the compressed gas come into indirect contact, so that the temperature of the lubricating oil increases the temperature of the gas through conduction, and the temperature of the gas decreases the temperature of the lubricating oil through conduction. In this way, the heat energy is recovered and utilized by increasing the temperature of the lubricating gas, and the temperature of the lubricating oil is reduced, thereby reducing the temperature inside the compression chamber.

[0023] (2) By cooperating with the active crankshaft and the driven crankshaft in the reciprocating compression assembly, the speed of the extension and contraction of the compression plate can be changed, so that when the compression plate contracts, oil can be slowly discharged through the oil seepage hole, and when the compression plate extends, the circulation of lubricating oil can be accelerated, and hot and cold alternation can be carried out.

[0024] (3) The up and down movement of the compression rod is converted into rotational kinetic energy through the oil guide assembly, which in turn allows the lubricating oil on the base plate to slowly pass into the compression shell through the oil seepage hole, reducing the amount of oil without affecting the degree of lubrication. Through the work of the compression plate, the lubricating oil is automatically added through the top, which can prevent the compression plate from being short of oil. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides two technical solutions:

[0038] Example 1

[0039] Figure 1-10The first embodiment is shown: a multi-energy complementary integrated energy supply system and energy supply method for large parks, including an air compressor 1, a drive motor 2, a cooling complementary component 3 for cooling and complementing the lubricating oil at the upper end of the air compressor 1, a reciprocating compression component 4 at the upper end of the air compressor 1, and an oil guide component 5 for automatic lubrication of the reciprocating compression component 4 at the upper end of the air compressor 1.

[0040] The cooling complementary component 3 includes a compression shell 301 fixedly installed on the upper end of the air compressor 1. The outer side of the compression shell 301 has a plurality of oil outlet holes 302 and oil seepage holes 303. There are six oil outlet holes 302 and oil seepage holes 303, which are evenly distributed in a circular pattern. A plurality of oil-fixing rings 304 are fixedly installed on the outer surface of the compression shell 301. The inner side of the oil-fixing rings 304 is connected to the outer side of the corresponding oil outlet holes 302 and oil seepage holes 303. An oil delivery pipe 305 is fixedly installed on the outer side of the oil-fixing rings 304. A complementary curved pipe 306 is connected between two oil delivery pipes 305. The position of the oil outlet hole 302 is lower than the position of the oil seepage hole 303.

[0041] In this embodiment of the invention, the reciprocating compression assembly 4 includes an active crankshaft 403 rotatably disposed on the inner surface of the compression shell 301. The curvature of the active crankshaft 403 determines the capacity of air compression per cycle. A transmission wheel 401 is fixedly disposed at one end of the active crankshaft 403 located outside the compression shell 301. A transmission belt 402 is rotatably disposed between the output shaft of the drive motor 2 and the transmission wheel 401.

[0042] In this embodiment of the invention, a driven crankshaft 404 is rotatably provided on the outer surface of the active crankshaft 403, a limiting ring 407 is fixedly provided on the inner surface of the compression shell 301, a compression rod 405 is slidably provided in the middle of the limiting ring 407, one end of the compression rod 405 is rotatably connected to the outer surface of the driven crankshaft 404, and a compression plate 406 is fixedly provided on the other end of the compression rod 405. The compression plate 406 slides on the inner surface of the compression shell 301.

[0043] Figure 5-7 Figures 9-10 show a second embodiment, the main difference from the first embodiment being that: the oil guiding assembly 5 includes a base plate 508 fixedly disposed on the upper end of the limiting ring 407, a conical shell 507 fixedly disposed on the upper end of the base plate 508, a sealing plate 509 fixedly disposed on the outer surface of the conical shell 507, a plurality of rectangular grooves being opened in the middle of the sealing plate 509, the upper surface of the base plate 508 being inclined, and the inclined directions of the base plate 508 and the conical shell 507 being the same, thereby preventing lubricating oil from accumulating.

[0044] In this embodiment of the invention, a plurality of extension springs 510 are fixedly provided on the upper end of the base plate 508, and a pneumatic block 511 is slidably provided in the middle of the rectangular groove. By moving the six pneumatic blocks 511, the air and lubricating oil between the base plate 508 and the sealing plate 509 are compressed, and the lubricating oil is squeezed out. The lower end of the pneumatic block 511 is fixedly connected to the other end of the extension spring 510. A driving tilt angle 512 is provided on the outer surface of the pneumatic block 511, and a circular hole for the compression rod 405 to pass through is provided in the middle of the conical shell 507.

[0045] In this embodiment of the invention, a curved groove 501 is formed on the outer surface of the compression rod 405, and an directional groove 505 is formed on the inner surface of the compression shell 301. A drive plate 502 is rotatably provided in the middle of the directional groove 505. A circular groove for the compression rod 405 to pass through is formed in the middle of the drive plate 502. A drive head 504 is fixedly provided on the inner surface of the circular groove. One end of the drive head 504 is semi-circular and slides on the outer surface of the curved groove 501.

[0046] In this embodiment of the invention, a plurality of oil leakage grooves 503 are provided on the inner surface of the drive plate 502, and a plurality of drive blocks 506 are provided at one end of the drive plate 502 near the pneumatic block 511. The lower end of the drive block 506 is provided with a transition rounded corner. The number of drive blocks 506 and pneumatic blocks 511 are equal. By setting them in equal quantities, multiple pneumatic blocks 511 can be triggered to move downwards at the same time. The end of the pneumatic block 511 near the drive block 506 is provided with a drive tilt angle 512.

[0047] In this embodiment of the invention, the upper end of the compression shell 301 is provided with an air exchange valve 6 for alternating gases, the output end of the air exchange valve 6 is fixedly provided with a pressure output pipe 7, the other end of the pressure output pipe 7 is connected to the inside of the air compressor 1, and the complementary curved pipe 306 is sleeved on the outside of the pressure output pipe 7.

[0048] A multi-energy complementary integrated energy supply method for large-scale industrial parks specifically includes the following steps:

[0049] Step 1: The drive motor 2 performs work, which in turn compresses the air through the reciprocating compression assembly 4. By cooperating with the air exchange valve 6, the gas is alternately discharged into the air compressor 1 through the air pressure output pipe 7. The air inlet end of the air exchange valve 6 is filtered to prevent impurities from entering the compression shell 301.

[0050] Step 2: When the reciprocating compression component 4 is compressing air, the cooling complementary component 3 circulates the lubricating oil inside the compression chamber. When the gas inside the compression chamber is discharged, it indirectly contacts the lubricating oil through the pipe, and the temperature alternates. When the lubricating oil contacts the air pressure output pipe 7, the lubricating oil can also contact the air along the way for cooling.

[0051] Step 3: The lubricating oil inside the compression chamber is circulated through the oil guide assembly 5. The lubricating oil is circulated by the kinetic energy of the compressed gas through the reciprocating compression assembly 4, which can reduce the temperature inside the compression shell 301.

[0052] In this embodiment of the invention, the lubricating oil in step 2 is fluorinated silicone oil or polyalkylene glycol. Fluorinated silicone oil or polyalkylene glycol is resistant to high temperatures and has good lubricity.

[0053] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0054] When in use, the operator turns on the drive motor 2 in the air compressor 1, which in turn drives the drive motor 2 to work. The drive motor 2 drives the transmission wheel 401 in the reciprocating compression assembly 4 to rotate via the transmission belt 402, which in turn drives the drive crankshaft 403 to rotate, which in turn drives the driven crankshaft 404 to move, which in turn drives the compression rod 405 to move. The compression rod 405 can only move up and down under the limit of the limit ring 407, which in turn drives the compression plate 406 to move up and down, and then compresses the air through the air exchange valve 6.

[0055] As the compression rod 405 moves up and down, it causes the curved groove 501 to move. This, in turn, causes the drive plate 502, limited by the drive head 504, to rotate in the middle of the directional groove 505. The drive plate 502 then moves multiple drive blocks 506. The lower end of each drive block 506 abuts against the upper end of the pneumatic block 511 at a drive angle 512. As the drive block 506 rotates, it compresses the pneumatic block 511 downwards. This compresses the gas and liquid between the base plate 508 and the sealing plate 509, causing the lubricating oil to be discharged through the oil outlet 302 and then entering the oil-fixing ring 304 outside the oil outlet 302. This allows the lubricating oil to enter the complementary curved pipe 306 through one of the oil supply pipes 305, then into the interior of the other oil supply pipe 305, and then into the solid oil ring 304 outside the oil seepage hole 303. After entering the interior of the compression shell 301 through the oil seepage hole 303, the lubricating oil descends to the upper surface of the compression plate 406 by gravity, lubricating the compression plate 406. When the drive block 506 disengages from the pneumatic block 511, the spring 510 extends and performs work, squeezing the pneumatic block 511 upward. This causes the oil inlet groove on the surface of the pneumatic block 511 to extend to the outside of the sealing plate 509, allowing the lubricating oil at the upper end of the sealing plate 509 to enter between the sealing plate 509 and the bottom plate 508 through the oil inlet groove.

[0056] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
